* Before you start changing something in this file be aware of the following:
20
* - There are several functions called recursively. In a very subtle and
21
* obscure way. DLLs can reference each other recursively etc.
22
* - If you want to enhance, speed up or clean up something in here, think
23
* twice WHY it is implemented in that strange way. There is usually a reason.
24
* Though sometimes it might just be lazyness ;)
25
* - In PE_MapImage, right before fixup_imports() all external and internal
26
* state MUST be correct since this function can be called with the SAME image
27
* AGAIN. (Thats recursion for you.) That means MODREF.module and
29
* - Sometimes, we can't use Linux mmap() to mmap() the images directly.
31
* The problem is, that there is not direct 1:1 mapping from a diskimage and
32
* a memoryimage. The headers at the start are mapped linear, but the sections
33
* are not. Older x86 pe binaries are 512 byte aligned in file and 4096 byte
34
* aligned in memory. Linux likes them 4096 byte aligned in memory (due to
35
* x86 pagesize, this cannot be fixed without a rather large kernel rewrite)
36
* and 'blocksize' file-aligned (offsets). Since we have 512/1024/2048 (CDROM)
37
* and other byte blocksizes, we can't always do this. We *can* do this for
38
* newer pe binaries produced by MSVC 5 and later, since they are also aligned
39
* to 4096 byte boundaries on disk.
